dict {
#quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
#expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext
}
# Most of the actual configuration gets included below. The filenames are
# first sorted by their ASCII value and parsed in that order. The 00-prefixes
# in filenames are intended to make it easier to understand the ordering.
!include conf.d/*.conf
# A config file can also tried to be included without giving an error if
# it's not found:
!include_try local.conf

And the lda part is in the /etc/dovecot/conf.d/15-lda.conf file and this is the content:

Code:

##
## LDA specific settings (also used by LMTP)
##
# Address to use when sending rejection mails.
# Default is postmaster@<your domain>. %d expands to recipient domain.
#postmaster_address =
# Hostname to use in various parts of sent mails (e.g. in Message-Id) and
# in LMTP replies. Default is the system's real [email protected]
#hostname =.
# If user is over quota, return with temporary failure instead of
# bouncing the mail.
#quota_full_tempfail = no
# Binary to use for sending mails.
#sendmail_path = /usr/sbin/sendmail
# If non-empty, send mails via this SMTP host[:port] instead of sendmail.
#submission_host =
# Subject: header to use for rejection mails. You can use the same variables
# as for rejection_reason below.
#rejection_subject = Rejected: %s
# Human readable error message for rejection mails. You can use variables:
# %n = CRLF, %r = reason, %s = original subject, %t = recipient
#rejection_reason = Your message to <%t> was automatically rejected:%n%r
# Delimiter character between local-part and detail in email address.
#recipient_delimiter = +
# Header where the original recipient address (SMTP's RCPT TO: address) is taken
# from if not available elsewhere. With dovecot-lda -a parameter overrides this..
# A commonly used header for this is X-Original-To.
#lda_original_recipient_header =
# Should saving a mail to a nonexistent mailbox automatically create it?
#lda_mailbox_autocreate = no
# Should automatically created mailboxes be also automatically subscribed?
#lda_mailbox_autosubscribe = no
protocol lda {
# Space separated list of plugins to load (default is global mail_plugins).
#mail_plugins = $mail_plugins
}

I had to add the "postmaster_address" manually in the protocol lda sectio

That´s what i wanted to know. Thanks. Currently i have no idea why you need this with OpenSUSE. On Debian you don´t need this value.

BTW: i don´t like the way the installer / updater checks postfix´s master.cf. Using grep or somethin similar may work.
Maybe we can switch to "postconf -M dovecot.unix" to detect the service dovecot in postfix.
